Finding GCD of 855, 157, 63 using Prime Factorization

Given Input Data is 855, 157, 63

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 855 is 3 x 3 x 5 x 19

Prime Factorization of 157 is 157

Prime Factorization of 63 is 3 x 3 x 7

Finding GCD of 855, 157, 63 using LCM Formula

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(855, 157) = 134235

GCD(855, 157) = ( 855 x 157 ) / 134235

GCD(855, 157) = 134235 / 134235

GCD(855, 157) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 63

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 63) = 63

GCD(1, 63) = ( 1 x 63 ) / 63

GCD(1, 63) = 63 / 63

GCD(1, 63) = 1

GCD of 855, 157, 63 is 1
